Application filed August 1a, 1923. Serial No. 657,027.

To all whom. it may concern:

Be it known'that I, Soorr E. ALLEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented anew and useful Spring Valve for Swingspout Measures,-

of which the following is a specification.

My invention relates to spring valves for swingspout measures such as are used at oil service stations for measuring lubricating oil and pouring the same into automobile crank case reservoirs. V v The general ob ect of my lnvention is to provide a measure of the character above stated including adjustable means for maintaining the measure valve fluid-tight undervarying conditions. 7 1 A more particular object is to provide resilient means bearing against the small end of one of the frnsto conical valve members ofa frusto conical valve to hold said member seated on the other valve member in fluidtight relationship therewith, and means for adjusting the pressure of said resilient means on said valve member as required to maintain such fluid-tight-relationship.

Further objects and advantages will be ,made evident hereinafter.-

Referring to the drawingwhich is for illustrative purposes only Fig. 1 is aside elevation partly broken I away and shown in section of a swingspout embodying my invention.

.Fig. 2 is a bottom plan view of said swingspout shown in Fig. 1. Fig. 3 is a fragmentary vertical longitudinal section of said swingspout taken on of the resilient valve engaging element.

In the drawing, l'indicates a casing; 2 a bottom; 3 a measuring receptacle formed by said casing and said bottom; 4 a rim extending below said bottom; 5 an outletconduit leading from the bottom of said measuring receptacle; 6 a conical controlling valve into which said conduit leads;7 a spout connected to said valve; 8 a measuring edge of the non-spill top of the receptacle 3; and 9 a handle secured to the rear of said casing; all of these parts being of standard construe tion. The rim 4 is bent inwardly from the front thereof in U-shaped formation as indicated at 10, forming the walls of a pocket extending inwardly from the front of the shell 12 and an outer frusto conical shell 13 seated and movable on said inner shell as abearing. The inner shell 12 extends longitudinally between the side walls of the pocket 11 and is jointed at its ends to said side walls, one of said side walls being provided with a valve inlet opening 14, through which the conduit 5 communicates with the inner valve shell 12. The inner valve shell 12 has an outlet port 15 and the outer valve shell 13 has an outlet port 16 in communication with the valve end of the spout 7, 'to which shell said spout is connected, the port '16 being closed by the wall of the inner valve shell 12 when the spout is turned into its upwardly extended position, (in which position the spout extends forwardly through the open front of the pocket 11 and upwardly in front of the measure, as shown 111 full lines in Fig. 1) and said port 16 being adapted to coincide with the port 15 when the spout 7 is turned downwardly as indicated in dotted lines in Fig. 1, in which latter position the valve is opened and the contents of the receptacle 3 allowed to pass out of said receptacle through the conduit 5, the valve shell 12, the ports 15 and 16, and the spout 7. I

A flat spring 20 is formed with aton e 21 at one end and a fork 22 at its ot er a end, said fork comprising a air of arms 23' the crotch 24 1 of said for between said arms being arcuate. The tongue 21 extends through a vertical slot 25 in the rear wall of the pocket 11 so that the fork 22 straddles the valve shell 12 near its small end with its arms 23, engaging the small end of the outer valve shell '13, the arouate crotch 2A: of said fork accommodating said shell 12. A set screw 26 is seated in one of the side walls of the pocket 11 in position to engage thespring20, for adjusting the pressure of said spring against said small end of said outer valve shell 13, to hold said outer shell firmlyeeatedtn the inner valve shell 12, whereby the shells 12 and 13 are maintained in fluid-tight ielationship under varying conditions.

I claim as my invntion;

1. .In a spring valve swingspout measure, a swingspout outlet valve comprising: an inner fixed member; an outer movable member disposed on said inner member, the ends of said inner member extending beyond the ends of said outer member; engagement means extending around said inner member and engaging an end of said outer member; and means for regulating the pressure of engagement of said engaging means with an end of said outer member.

2. In a spring valveswingspout'measure, the combination of a frusto-conical swingspout outlet valve comprising an inner member and an outer member; a flat spring engaging the small end of the outer frustoconical member of said valve for maintaining said member firmly seated on the inner frusto-conical member of said valve; and a set screw engaging said fiat spring for varying the pressure ofsaid spring against said frusto-conical valve member, as conditions require to hold said outer conical valve member firmly seated on said inner conical valve member, said outer valve member being movable upon said inner member as abearing.

3. In a spring valve swingspout measure, the combination of a frusto-conicalswin gspout outlet valve comprising an inner member and an outer member; a fiat spring formed with a tongue on one end for engaging a slot in a wall of the measure for holding the other end of said spring in engagement with the small end of the outer frusto-conical member of said valve for holding said outer member firmly seated upon said inner valve member.

4. In a spring valve swingspout measure, the combination of a frusto-conical swingspout outlet valve comprising an'inner member and an outer member; a flat spring formed with a tongue on one end for engaging a slot in a wall of the measure for holding the other end of said spring in engagement with the small end of the outer frustoconical member of said valve for holding said outer frusto-conica-l member firmly seated upon said inner frustoconical valve member; and means for engaging said fiat springs for adjusting the pressure thereof against said small end of said outer valve member as conditions require.

5. In a spring valve swingspout measure, the combination of a swingspout outlet valve comprising a fixed inner member and a n'iovableouter member; a fiat spring formed with a tongue on one end for engaging a slot in a wall of the measure for holding the other end of said spring in engagement with the small end of the outer member of said valve for holding said outer member firmly seated upon said inner conical valve member; and a set screw for engaging said flat spring for adjusting the pressure thereof against said small end of said outer valve member as conditions reuire. q 6. In a spring valve swingspout measure, a swingspout outlet valve comprising: an inner fixed frusto-conical member; an outer movable frusto-conical member disposed on said inner frusto-conical member, the ends of said inner frusto-conical member. extending beyond the ends of said outer frustoconical member; engaging means extending around said inner frusto-conical member and engaging the small end of said outer frusto-conicalmember; and means for regulating the pressure of engagement of said engaging means with the small end of said outer frusto-conical member.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 6th day of August, 1923.
